Meta-analysis has increasingly been used to synthesise the environmental valuation literature, but only a few test the use of these analyses for benefit transfer. These are typically based on national studies only. However, meta-analyses of valuation studies across countries are a potentially powerful tool for benefit transfer, especially for environmental goods where the domestic literature is...

A 2011 survey of Mexico City’s households revealed that families prefer alternative sources of drinking water instead of relying in the city’s quality supply services. These include the purchase of bottled water, installation of filtration devices, and other means of water purification. The demand for better water quality was tested by estimating the household’s willingness to pay (WTP), using ...

Development of downstream operations in the Iran's petroleum industry has always been considered as a necessity in to create more value-added. One of ways to accomplish the misson, especially in the current situation, is exploiting the capacity of petroleum startups. Considering that these companies need to be valued for financing, and since the traditional valuation methods do not provide effi...

Adam Smith’s farmworker paradox reflects the fact that those who do the most essential work in society earn the least, just as his diamonds and water paradox revolves around the low valuation that markets place on essential resources. This article explores the perverse economic logic that leaves markets to run roughshod over both humanity and nature. It also explores how economists either attem...

In South Korea, the Soyang Lake is an important source of drinking water to the metropolitan areas including Seoul. However, water quality problems in the Soyang Lake have still remained due to chemical contaminations attributed to conventional farming practices in the upstream areas. Based on a downstream consumer survey using a contingent valuation method, this study estimated the expected wi...

Proposition algebra is based on Hoare’s conditional connective, which is a ternary connective comparable to if-then-else and used in the setting of propositional logic. Conditional statements are provided with a simple semantics that is based on evaluation trees and that characterizes so-called free valuation congruence: two conditional statements are free valuation congruent if, and only if, t...

The brand is a very special asset and in many businesses it is the most important asset. This is due to the farreaching economic impact that brands have on enterprise. Brands influence the choice of customers, employees, investors and government authorities. In a world of abundant choices such influence is crucial for commercial success and creation of shareholder value. Even non-profit organis...

let r be a ring and v be a matrix valuation on r. it is shown that, there exists a correspondence between matrix valuations on r and some special subsets ?(mvpr) of the set of all square matrices over r, analogous to the correspondence between invariant valuation rings and abelian valuation functions on a division ring. furthermore, based on malcolmson’s localization, an alternative proof for t...
